Hmm….It looks like the digital encrypted currency exchanges have some bugs to work out!

For a case study of a blistering rise and an absolutely epic fall of an exchange that i) was named after Magic: the Gathering and ii) transacted in a digital currency which many have speculated wasconceived by the NSAnearly two decades ago and was used as a honeypot to trap the gullible, look no further than Mt.Gox which after halting withdrawals for the second (and final time) has finally done the honorable thing, and filed for bankruptcy. As the WSJ reports, “Bitcoin exchange Mt. Gox said Friday it was filing for bankruptcy protection after losing almost 750,000 of its customers’ bitcoins, marking the collapse of a marketplace that once dominated trading in the virtual currency. The company said it also lost around 100,000 of its own bitcoins. Together, the lost bitcoins would be worth approximately $473 million at market prices charted by the CoinDesk bitcoin index, although the price of Mt. Gox bitcoin had fallen well below that index after it stopped bitcoin withdrawals in early February.”

The punchline: speaking to reporters at Tokyo District Court Friday after the bankruptcy filing, Mt. Gox owner Mark Karpelès said technical issues had opened the way for fraudulent withdrawals, and he apologized to customers.

“There was some weakness in the system, and the bitcoins have disappeared. I apologize for causing trouble”

Mr. Karpelès, wearing a gray suit and a blue tie, appeared calm while his lawyer did most of the talking, but he appeared to have difficulty finding words when reporters asked him to send a message to his investors, just repeating his apology.

Computer geeks who were hoping to ride the momentum train to riches, and apparently had never heard of gold, were unhappy:

“It is disappointing they hid so much for so long,” said Jonathan Waller, a 30-year-old game developer who said he had had 211 bitcoin in Mt. Gox. “I hope they manage to become a fully-functioning exchange again, but their reputation is so damaged it may not be possible,” he said.

Over the past month, customers from as far away as the U.K. and Australia had come to air their complaints outside the company’s Tokyo offices. One of them, Londoner Kolin Burges, figured in news photos around the world holding a sign saying, “MT GOX—WHERE IS OUR MONEY.”

William Banks, a website developer in Australia, said he lost about 100 bitcoins in Mt. Gox. He had been using the platform since the end of 2012, when he bought some bitcoins at $40 each. Recently, he bought more at about $800 a pop as he became more confident in the virtual currency. He said he has contacted a Japan-based lawyer to look into legal action.

About Mt. Gox’s loss of bitcoins, he said, “That seems impossible to me. It’s just such an astronomical amount of coins to lose.”
